styles of engines. In fact, my invention vmay be lema ployed `for furnishing motive power to any type ofengine operated by the expansive force of gases.

`The primary object of my invention is to provide means for generating a gas, or gases, in a chamber or chambers separate from the engine, -or other machine to be operated by the gas or gases produced, and afterwards conductingthe live gases to the -engine and utilizing them for motive purposes.

A further object is to provide for maintaining a practically constant pressure on the engine, by means of the gases generated as above described, so that the ac- I tion of the engine Willbe constant and uniform, just as is the case where steam is employed as the motive force.

In the apparatus illustrated in the drawings and lene, except in so far as such features are specifically claimed, as many of the features which adapt the apparatus for use with gasolene are also well adapted for use when other substances 'are employed for-generat iiig the gases. 7 v

The apparatus illustrated in the drawings consists,

generally, of a plurality f reservoir cylinders which are similar in construction and are arranged to coperate in maintaining a practically constant pressure on thel engine.

them from cylinders such as the cylinders of an ordinary explosive enginelwhich communicate directly with the piston chamber, so that the force of the explosion is applied directly to the piston and the full.

force of the explosion is applied thereto immediately upon the taking place of the explosion. The cylinders of my improved generator, on the other hand, do

not discharge completely as soon as theexplosion takes place, but act as reservoirs to hold the exploded gases and to supply them foruse as they are required, as will fully hereinafter appear. While the cylinders of my improved generator thus act as reservoirs, the period for which the gases are retained'by them may vary to a considerable extent,as it will depend largely uponthe I term the cylinders which compose the generator reservoir cylinders, in order to distinguish number of cylinders employed; but whether itv bc for a very short time or for a long time, they nevertheless.

act as reservoirs. Said reservoir cylinders are arranged in series and operate in tum,-thatis to say, if four cylinders are used, when the rstone explodes the second an'd third will be preparing for the next explosion by receiving charges of air and gasolene, while the fourth will have exploded just previously. Furthermore, the different cylinders are so connected andarranged that their operation is interdependent, the 0peration of each cylinder being controlled entirely by the operation of the others in the series. The entire series of cylinders, constituting the generator, is connected towhat is the equivalent of the steam chest of the engine, by means o f a reducing valve which reduces th initial pressure of the gases as producedin the reservoir cylinders to a comparatively low point, thus conserving the energy and supplying power continuously during the intervals between the explosions in the different cylinders. By varying the number of cylinders in the series, the interval between explosions may, of course, be varied; but the principle is the-same, whether the number. of cylinders be two or more. It will be understood that the term cylinder is used generically, to describe a single generator of the series: the term generator being used to indicate the whole composed of the series of interdependent cylinders. v The foregoing is a statement of the general construction and operation of my improved generator, and I will now describe, in detail, the generator as illustrated and described inthe accompanying drawings.

Referring to the drawings,-Figure 1 is a plan view of the generator, illustrating also part of an engine and a blower operated thereby; Fig. 2 is an -underside View of the generator; Fig. 3 is a sectional view of the cylinders composing the generator and certain parts ofthe valve mechanism; Fig. 4 isan enlarged longitudinal section of one of the cylinders, and the various attachments operating in connection therewith; Fig. 5 is a similar view, showing the cylinder at a different stage of its operation; Fig. 6 is an enlarged detail, being a longitudinal vertical section of part of the circuit-closing mechanism; Fig. 7 is an enlarged sectional view of the injecting apparatus and its connections; Fig. 8 is an'enlarged detail, partly in secbtion, showing one ofthe circuit-closing devices in side chest 16 which corresponds to the steam chest of anA .engine 17. Between the pipe 15 and the chest 16 is a reducing valve 18,v oi any approved type, operating to control the pressure of the gases admitted to said chest.

B-CD. Said pipe is connected to said cylinders by 4stubs a", b c and d and in each of said stubs is provided a valve chamber 22 in which is a check lvalve 23 operating to-admitair from the pipe 21to the cylinders A-B-C-D and to prevent reverse flow thereof. v The pipe 21 is connected with a blower 24. of any suitable construction, said blower being provided with a crank 25 connected to the pitman 26 of. the engine 17, so that as theengine 17 operates, the blower 24 is also operated tovforce .a current otain vthrough-the'pipe v214v and into the'cylinders A ---eG-D, as-1 will be hereinafteridescribed.. Insteadof operating the blower 24 vfrom the engine 17 it may be otherwise operated.

At the end oi each cylinder-opposite that to which are securedl the stubs" above described, there is pro.-

vided an outletvalve, v'marked a?, b2, c2,-and olri'aspe@l tively, each of saidz-valves consisting ofavalv'e chamber 27 communicating with the interior ofv the :cylinder andhaving a valve-seat 28 on which iss'eated adisk 29 having a stem 30 .which projects down throughthe valve casing, as best shown in Fig. 4; the arrangement being such that when the disk- 29 is on its seat the esi cape lof air or gas from the cylinder in that direction is. prevented.

In each valve, below the valve-seat 28, yare perforations 3l through which the escaping air or gas passes out of the casing. Below each of the valves a2, b2, c2 and d2' is secured a frame 32, in the nature of a tripod, which carries a pressure chamber, said pressure chambers being marked, respectively, a"-b"`-v c3--d3- Each of said pressure ohamberaconsists of a rigid plate 33, concave on its upper surface and having secured thereto a thin flexible disk` or diaphragm 34, as shown inv Fig. 4. The edges of the disk 34 are secured to the plate 33 by a ring 35. A chamber 36 is thus formed between the disk 34 and the plate 33, as shown. The-lower end of-ea'ch of the stems 30 rests upon the disk. 34, being'littedinra suitable socket a b oss 37- provided orthat purpose,.asshown in 4; and around leach of thel stems 30, between the disk H 34 and the valve-casing above it, is a. spring 38 which and prevent 'the escapeofgas or air throughl the valves a?, b2, c2 and d2,'-respectively. By raising the lflexible disk 34,'whichisiaccomplished by introducing may be raised to carry thedisk 29 gas under pressure into the chamber 36, the'ste'm30 the valve.

The pipe connections, vby which the pressure-channbers a3, b3, cfand dJ are operated, are bestv shown. in

Fig` 1, froman inspection of which-it will be seen that four T-couplings are provided, marked, respectively, 39-40-41-42. The coupling 39 is connected by off its seat andopelr I pipe 43 with the cylinder A and by pipe 44 with the cylinder B, which pipes are secured in opposite arms of said coupling. 45 indicates a pipe, which is conplate 33 of the pressure chamber d3. The coupling 40 v is connected to cylinders B. and C by pipes 46-47, re-

spectivel'y, which are secured in opposite arms of the coupling 40, as shown. The stem oi the coupling 40 is connected 'by a pipe 48 with the plate 33 of the pressure chamber a3. Similarly, the coupling 4]. is connected by pipes 49-50, respectively, withthe'cylinders A and D, the stern ofsaid coupling- 4l being connected by a pipe 51 with the plate 330i .the pressure chamber c.4 In like manner, the'coupling 42 is connected by pipes 52-53fwith the cylinders C and D respectively; the stem of said coupling 42 being connected. by a pipe '54" with the plate 33 of the pressure `chamber b3.

The construction of each of the couplings 39--40- 41-42 is best shown in Fig. 10. The coupling show-n inFig. l0 is marked for convenience 4l; but it'will be understood that' the others are identical in construcsitely-extending arms 55-56, and that the pipes 49 -50 arefscrewed intosaid arms-,.respect ively. It will also Vbe seen that the stem 5 7 of the coupling is screwthreaded and receives the end of the pipe 5l. The center of the coupling is'provided with an elliptical valve-chamber 58, which carries `a ball-valve Sil-adapted to be seated4 in one or.l theother of the ends of the valve chamber 58, as shown. indicates a port, opening from the valve-chamber 58 into the pipe 49;

62 indicates a port opening from the bottom. of the valve-chamber -58 into pipe 5l. The arrangement is such that when the valve59 closes the port 60,v ports 61 and 62 are open, while, when the valve 59 closes port 6l, ports 60 and 62 are open. 63 indicates a screwcap for the coupling' 41, by. the removal of which access may be had to the valve-chamber 58 for the removaLor insertion of the-ball valve. Y

The pressure chambers a-b-frl-d'l, in addition to operating thevalves 29 as already described, also operate the circuit-closing devices a4-b-c4-d respectively, as shown in Figs. 1 and 8. Each of said mountedon apivot 64 suitably secured on the frame 32, one arr'n of -each of saidycircuit-closing devices extending toward the en'dy of the adjacent cylinder, the

stem 30 and engagnga pin 65 carried by said'stem, being providedivwithaffork A66 forthatpurpose, (see Figs. 4 and 5l) The endnoff each of the circuit-closing devices whichfextendstcward the cylinder is-A provided from. eachother and. from the' armfon which they are .blocks 67-1-68is exposed, as shownin Fig. 8;- andthe exposed surfaces of .the two blocks G7-468, carried by each of the circuit-closing devices, are vadapted to engage two pairs of springl brushes'or'cntact points .70'71,727.3 projectingfrom the. end ofthe adjacent cylinder, as shown in Fig. 8. The springs 70-71 are insulated from each other, the insulation being indiand 6l indicates a similar port opening into pipe 50` circuit-closing devices consists of a bell-crank lever' withv two-metal1ic=blocks67?68, which lare insulated' nected to the stem of the coupling and runs to the vtion with it. `From an4 inspection of Fig. 10 it will be seen thatv the couplings are provided with two oppo-4 l 1 1 5' other armi-,hereof extending toward the adjacentl valvei cated by 74 in Fig. 9; and said springs project in the path of the circuit-closing devices, so that when said circuit-closing devices are rocked on their pivots, they will strike said springs and deflect .them temporarily in passing. The exposed contact surfaces of the blocks are so placed that when the valve-stems30 move downward, carrying the contact bloc-ks 67-68 inward, the

' exposed surfaces of said blocks will strike the sp1-ings tions of the different switches will be hereinafter explained. The function of the switches l5-a, b5-b6, c-ci and dddG is to provide for the ignition of the gases in the different cylinders, at the proper time; and this is accomplished through electrically-operating devices which will now be described.

From an inspection of Figs. 4 and 5 it will be seen that each of the cylinders A-B-C-D is provided near one end with a sparking apparatus, consisting of an insulatedrod 75, preferably of copper, the inner end of which projects into the cylinder and is provided with a platinum tip 76, as shown in Fig. 6. The rod 75 is in` sulated by being fittedinto a sleeve 77, of porcelain or other suitable insulating material. Preferably, the sleeve 77 is in two sections, one being above and the otherbelow a collar 78 carried by the rod 75 and located about midway thereof, as shown in Fig. 6. The sleeve 77 is in turn inclosed in vulcanite sleeves 79-80 fitted tightly'thereon; and between said sleeves there is a vdisk 81, also of porcelain, said disk being inserted below the collar 78 of the rod 75. The sleeves 79-80 are fitted in a brass plug 827 screwed into the cylinder and provided with a cap 83, as shown. Suitable gaskets 84-85 are provided in the plug to secure the sleeves 7 9-80 firmly in position. The collar 78 prevents the rod 75 from moving down too far. The upper end of the rod 75 which projects above the cap 83,l is provided with a cap 86, of brass or other suitable conducting material, which also inc'loses the upper ends of the sleeves 'Z9-80, as shown.v 87 indicates a platinum wire, which is secured to the plug-82 and terminates near the tip 76. By adjusting the position of the rod 75 the space-between the tip 76 and the wire 87 may be adjusted, to vary the length of the spark. The adjustment of the rod 75 may be effected by using gaskets' 84 of different thicknesses. 88 indicates arod, of vulcanite or other non-conducting material, which is secured to a support 89 mounted on a pivot 90 carried by a suitable frame 91 mounted ona standard 92 of insulating material, which is secured on the surface of the cylinders in proximity to the sparking devices already described, as shown in Figs. 1 and 6. The frame 91 is securedto the standard A92 by a screw 93 which passes through the upper portion of the standard into the frame, V as shown in Fig. 6. The frame 91, support 89 and pivot 90 are of conducting material; and said frame is provided with a bindingpost 94. 95 indicates a rod, of copper or other conducting material, which extends from the support 89 through the rod 88 and connects with a cap 96 at the end of the rod 88; said cap 96 being arranged in position to strike .within the cylinder.

vthe cap86 of the sparking-device when the rod 88 is rocked suf'liciently in the proper direction., 97 indi.-

and 6. It will thus be seen'that by energizing the electro-magnet 98 it will attract the armature 97,- carrying the rod 88 downward and moving the cap 96 intocontact with the cap 86, thereby closing the circuit from the binding-post 94 to the tip 76.

In Fig. 11 the electro-magnets 98 of the differentl cylinders -A-l--C-D are respectively indicated by 117-67, c7 and-d7, and each of said magnets is connected with one pole of an electric battery 99; the magnet a7A having a wire 100 which connects it with said battery, the other magnets being connected thereto, respectively, by Wires 101, 102 and 103. The-opposite pole of the magnet a7 is connected by a wire 104 withthe contact point of the switch b". Similarly, the magnet b7 is connected by a wire 105 with contact point 70 of the switch c, the magnet c7 by a wire 106 with contact point 70 of the switch a, and the magnet d7 by a vwire 107 with Contact point 70 of the switch a5. 108 indicates a wire which connects the contact point 71 of the switch a( with Contact point 71 of the switch d". 109 indicates a Wire which connects contact point 70 ofthe lswitch dwith the opposite pole of the battery 99 from that to which the wire 100 is connected. 110 indicates a wirevwhich connects contact point 71 of the switch bf with contact point 71 of switch c5. 111 indicates a Wire which connects contact point 70 of switch c" to wire 109. 112 indicates a wire which connects Contact point 71 of switch ctovcontact. point 71 of switch d".

113 indicates a wire which connects contact point 70 -poles of the secondary coil of the induction coil with the binding-post 94 carried by the different cylinders.

For convenience, in Fig. l1, the different bindingposts are indicated by letters a", b, c and d8. 120 indicates a'wire by which the opposite pole of the 'secohslary coil of the induction coil 116 is grounded in the cylinders A-B-C-D, thus securingclectrical connection with the platinum wires 87 in the different cylinders. l

From the foregoing it will be seen that when the rod 88 moves down'far enough to bring its cap 96 into contact with the cap 86 of the sparking-devices, connections will be made extending from the tip'76 through rods and 95, .wire 119, and through the secondary coil of the induction coil 116, wire 120 and the body of the cylinder to the platinum wire 87, thereby causing a spark The manner in which the different switches are operated to energize the different electro-magnets a7, b7, c7 and d7, to effect the result just described, will be hereinafter set forth.

The object of causing the sparks in the different cylinders is to ignite a mixture'of air and vaporized gasolene therein. The air is introduced into the cylinders through pipe 21 by means of the blower-24: the gasolene is introduced through a pipe 121 and atomizers a", b9,

cates an armature carried bythe rod 88 over an electromagnet 98'sec11red on the cylinder, as shown i'n- Figs. 1',

c9 anelli?, respectively? The term atomizers is apl plied; to -the gasolene-feeding devices in a genericsense-','an'd-,as herein used, it should be understood that itl does not apply .solely to the atomizing mechanism. The construction ofthe atomizersis best shown in 7, in which a sectional View of the atomizer a9 is. shown in position on the cylinder A. The atomizers are all alike, so that, a description of a-single one will suffice for all. From an inspection of Fig. 7 it will be seen that there is an external cylinder or casing 122, one 'endoi which is externally and internally screwthreaded, the external screw-thread screwing into the.

cylinder A` A cap 123 is screwed into the internal screw-threads, as shown, said cap being provided with a curved nozzle 124 which discharges into the cylinder, the opening being so turned as to direct the inflowing gasolene lengthwise of the cylinder and toward the end at -which the valve 29 is placed; the object being to more v thoroughlydisseminate the atomized gasolene throughout the cylinder. A passage.125 is provided in the cap 123 within the nozzle 1 24 for the passage of gas from the chamber 126 formed by the casing 122 into said nozzle 124. 127 indicates a gasket placed between a circumferential flange 128 carried by the cylinder 122 and the cylinder A, so as to make a tight joint. The

A'other end of the cylinder 122 is contracted, as shown at 129, and externally screw-threaded to receive a coupling 130 which secures thereto a stub 131 communicat-v ing with the pipe 121. The contracted portion 129 of the cylinder 122 contains a valve-chamber 132, partly separated from the chamber 126 by a diaphragm'133 having a central passage which affords communication between said chambers 126 and '132, At the opposite end of the chamber 132 from the diaphragm 133 is a valve-seat 134. 1 135 indicates a valve-cylinder which isplaced within the cylinderfr122 and is of somewhat less diameter, being held in position by vwings 136 which radiate therefrom at suitable points, as shown; The inner end of the valve-cylinder 135,-that is to say, thc end nearer ,the cylinder A,is provided with a screw-cap 137 which has a central passage 138 which registers with the passage 125. A tube 139 extends through the passages 125 and 138, one end terminating in the lower portion of the valve-cylinder 135, the other end being curved and extending to near the discharge end of the nozzle 124, as shown. The tube 139 does not entirely close the passages 125 and 138, sufiiv cient space being left around it to permit the action of the gases under pressure, as hereinafter described, on

the liquid in thevalve-cylinder and inthe nozzle chamber 132 into the tube 140', and through it into the valve-cylin`der 135.

The power which operates the atomizer oi any-given cylinder is derived ironi-Y the explosion in one vof the other cylinders. For example, the action of the atom'- izer a" depends upon the' explosion' in the cylinder D;

lseaass b1 which connects with the atoinizer c, and the cylindcr C with a pipe am which connects with theatomizer d, (see Fig. 2)'. Between each of the pipes a, b1, cm and dl and the atomizerszto which they are respectively connected, are provided check-valves. 143, as shown in Fig. 7 Said'check-valv'es may beof any approved construction suitable for that purpose.4 In Fig. 7 1 have illustrated them as consisting of aball having a conical stem 144 seated on a seat 145 separating. passages 1.46 and 147; the former leading,'-in the instance shown in Fig. 7, to the pipe d10 and the-latter leading to the chamber' 126, the arrangement being such that when there -is pressurel in the passage 146 the valve 143 is lifted from its seat, permitting the gases to v flow thrqugh passage 147 into chamber 126, andthencethrough passages 1,2 5 and v138to the nozzle 124v and.

valveecylinder 135, respectively,v -theigases'acting-.to'

"atomize or spray the liquid:v in the valve-cylinder 135 into-thecylindcr A, as` will be hereinafter described.`

[The operation of.' myv improved generator is-as folbe 4preparing therefor, andy theucylinders B and C will b'efreceiving a charge ofvresh airjto' clear out the gases lremaining after the explosion. and to-supply arequisite amount of air' for mixture .iwiththe gasolene,prior to the next explosion. At this-time, as shown in Fig. 3, the valves 29 in valve-chambers a2 and d2 will lbe closed,

while thevallves in tlrechambers b2 and c2 will be' open. -This will be due tothe fact that, as the pressure in cylinder D will be greater than in any-:other cylinder owing to its just having exploded, such pressure will force the ball valves 59 inlcouplings 41 and 42 against the seats at' the ports 60,'perrnitting the gases in cylinder D to act through pipes 53-and54 on: diaphragm b3, and also through pipes 50 and 51 on. diaphragm c3,

lthereby forcing thedisks 3415i saidv'diaphragms upward, and opening their' respective valves 29.- The valve 29 in valvefcharnbcro2 wi-ll be -closed at 'the time of the explosion-in cylinder' D by the springs 38,

since` there willlbe no opposingv pressure in-the -diaj phragm a3, as'will'liereinafter appear.v j When the explosionoccurs inthe cylinder D, pressure'will be transmitted `through pipe di? to atomizer a9, tlr'e valve 143 being, raised thereby sothat the gases under pres sure enter the chamber 126.Av Prior to this action, the

valve-cylinder 135 will `have received azchargeof gasocient to fraise the valve 141 from: its. seat, so that the v gasolenel can enter the valve-chamber132, and passing through it" and through 'thepipe` 1411enter the .valvecylinder 135.'l As illustrated in Fig. 4,*the atomizers are on the under side of their respective cylinders,

pressure on the surface ofthe gasolene therein con-- tained, forcing the gasolene up through pipe 139 and out through the nozzle 124. At the same time, the

gases pass upward through the passage 125, and act externally on the gasolene escaping from pipe 139; the result being that the gasolene is atomized and sprayed through the cylinder into which it is discharged. The

' check-valve 143 is provided with a large ball 149 which prevents it J:from rising from it's seat except under the ,greatest pressure, so that the gasolene is supplied to the lcylinders only immediately after the explosion in the cylinders which exploded next previously. Waste of pressure is by this means avoided. A spring could be used instead of the weight 149, if desired. The

atomizors b9 and c9 of cylinders B and C, respectively, will not supply gasolene to their respective cylinders at this time, although their valve-cylinders 135 will be full or be filling with gasolene, because there will be no pressurevv in cylinder A, which operates atomizer b", or in cylinder B, which operates atomizer e9. It will, of course be understood that cylinder A was cleared of gases and provided with a charge of. fresh air prior to its receiving a charge of gasolene, the air being supplied to said cylinder at the time of the explosion in cylinders B and. C.

As has already been explained, the pressure chamber a3 of cylinder A, by which its valve 29 in Valvechamber a2 is opened,A is connected by pipe 46, coupling 40 and pipe 48 with cylinder B, and by pipe 47, coupling 40 and pipe 48 with cylinder C, so that presspre in' either of said cylinders B and C sulicient to compress spring 38 operates to raise the disk 34 in pressure chamber aa and open valve 29 in valve-chamber a2. Since the cylinders A--B--C-D explode in rotation, prior to the explosion in cylinder D the explosion in cylinder C will, therefore, have opened valve 29 in valve-chamber a2, and until shortly'before the explosion in cylinder D said valve will have remained open. As soon, however, as the pressure in cylinder C is reduced to such an extent that it is unable` to hold the spring 38 of pressure chamber aa under compression, said spring acts to depress the disk 34 and valve-stem 30, closing said valve 29 and putting the cylinder A into condition to receive its charge of gasolene. This occurs shortly before the vexplosion in cylinder D. Im-

mediatelyv upon the taking place of the explbsion in.

' cylinder D gasolene is sprayed into cylinder A, as already described, and at the same time the pressure chamber disks 34 of the pressure chambers b3 and c3 are raised, pressure being applied to the pressure chamber b3 from cylinder D through pipe 53, coupling 42 and pipe 54, and to the pressure chamber c3 through pipe into the position shown in Fig. 1. When the pressure in cylinder D is reduced by consumption to such a point that itis insuicient to compress the springs 38 of the pressure chambers b3 and c3, said springs act to close.the valves in the valve-chambers b2 and c2, moving their respective valve-stems 30 downward, rocking the circuit-closing devices b4 and c4 to the right, as

shown in Fig. 1, and moving them temporarily into engagement with the springs 70-71 and 72-73 as they pass. This closes the circuit at switches b5, b6 and c, c,

so that there is then a circuit from battery 99 through no current passes through them, since these circuits are l broken at other points, as, for example, at a5 and d5.

The closing of the. circuit through magnet a7 causes the rod 88 to move toward the'cap 86 of the sparking devices of cylinder A until the 'cap 96 strikes said cap 86, thereby making connection between the induction coil 116 and the tip 76 in one direction, and between the induction coil and the wireA 87 in the other direction, thereby causing a spark to pass from the tip 76 to the wire 87 within the cylinder A. The connections between the induction coil and the tip 76 are as follows: over wire 119 to binding-post a8, thence through rod 95 to cap 96, thence to cap 86 and through rod 75 to tip 76. From the induction coil to wire 87 the current passes over. wire 120 to the frame of the machine, and through said frame to the wire 87. The closing of the circuit in cylinder A will ignite the mixed air and gasolene therein, which will explode, the greater portion of the power being directed through pipe 15 to the chest. At thev same time the pressure in cylinder A will act through pipe 49, coupling 41 and pipe 51 upon pressure charnber c3, raising the disk 34 thereof and again opening the valve 29 in chamber c2. It will also act through pipe 43, coupling 39 and pipe 45 upon pressure chamber d3, raising the disk 34 thereof and opening valve 29 in valve-chamber d2. It will also act through pipe al upon atomizer b i of cylinder B, and effect the discharge thereinto oi the gasolene in its valve-cylinder 135. The valve 29 inthe valve-cylinder b2 will, however remain closed, since it is not acted upon by pressure in cylinder A, so that the gasolene supplied to cylinder B will not pass out. When the valve 29 in the valve- 'chamber d2 of cylinder D is opened, as above described, there being no pressure in said cylinder, checkvalve 23 which controls the air discharged from the blower will open, admitting a supply o fresh air which will enter and fill said cylinder, passing out through valve 29 and passages 31 until said valve is again closed.

The operation of the different cylinders continues in rotation; the gasesin cylinder B exploding as soon as the pressure in cylinder A becomes -reducedfto a point where it is insufficient to compress the'springs 38 of pressure chambers d3 and c3, when said springs will rock the circuit-closing devices d4 and c4,respectively, closing' the circuitthrough switches c5 and c and al5 and d, thus establishing a closed circuit through vmagnet b7 as follows: from battery 99 over wires 100 and 10] to magnet blkthence back over wire 105, switch c, wire 112, switch d5 and wires 113 and 109 to the battery. This energizes magnet b7 and causes a spark in cylinder B, as already described, inconnection with cylinder A. In like manner an explosion in cylnder B opens valves 29 in valve-chambers d2 and a2, and the conseqilent reduction of pressure in cylinder B closes the circuit by means of circuit-closing devices d4 and a4, respectively, through switches d""--d6 and a-a, establishing a current through magnet c7 from the battery 99, as follows: over wires 100 and 102 to magnet 67, thence back over wire 106, switch a, wire 108, switch d6 and Wire 109 to the battery, making a'spark in cylinder C and causing an explosion therein. It will thus be seen that the different cylinders explode in rotation, and

that in the construction shown three cylinders are being cleansed and charged for subsequent explosions While the fourth is under pressure, so that practically a continuous pressure is maintained on the chest. It will further be seen that by regulating the tension of the springs 38, the minimum'pressure in the cylinders can be accurately regulated. l

Obviously, the number oi cylinders A-B-C-D employed may be varied in number, from two up being used; but it is desirable that the number employed be suiicient to allow ample opportunity for the cleansing and charging oi the cylinders between explosions. It is further obvious that the ditierent cylinders may be arranged to explode in any desired order by appropriately arranging the connections; but, for convenience, it is desirable that they be arranged in the order illustrated.

The engine is stopped and started by means of a throttle valve 148 placed between the pipe 15 and the chest 16 of the engine, and preferably between the reducing valve 18 and the chest, as indicated in Fig. 1. When the valve 148 is opened the gases under pressure may enter the chest 16 and operate the engine; and by closing said valve pressure may be cut 0H from the chest. When the throttle valve is closed, the cylinder in which the last explosion took place will retain its gases under pressure, since-the different valves are made tight enough to prevent leakage. The result is that the engine may be started at any time by simply opening the throttle valve, and the generator will commence its operation at once, the different cylinders operating as hereinbefore described. f

The term engine, as used herein, should be understood to mean a machine, of whatever character, operated by power derived from the generator.
